Who leaked the Panama Papers? A famous financial whistleblower says: CIA.

There are many conspiracy theories about the source of the Panama Papers leak. One of the more prominent theories today blames the CIA. Bradley Birkenfeld is “the most significant financial whistleblower of all time,” and he has opinions about who's responsible for leaking the Panama Papers rattling financial and political power centers around the world.

Why? Look at who's most affected, he argues. Countries that aren't on great terms with the US.

"The very fact that we see all these names surface that are the direct quote-unquote enemies of the United States, Russia, China, Pakistan, Argentina and we don't see one U.S. name. Why is that?" Birkenfeld told CNBC. "Quite frankly, my feeling is that this is certainly an intelligence agency operation."

Wikileaks is also getting attention today for blaming USAID and George Soros for the leaks.

From CNBC:

Birkenfeld, an American citizen, was a banker working at UBS in Switzerland when he approached the U.S. government with information on massive amounts of tax evasion by Americans with secret accounts in Switzerland. By the end of his whistleblowing career, Birkenfeld had served more than two years in a U.S. federal prison, been awarded $104 million by the IRS for his information and shattered the foundations of more than a century of Swiss banking secrecy.

In an exclusive interview Tuesday from Munich, Birkenfeld said he doesn't think the source of the 11 million documents stolen from a Panamanian law firm should automatically be considered a whistleblower like himself. Instead, he said, the hacking of the Panama City-based firm, called Mossack Fonseca, could have been done by a U.S. intelligence agency.

"The CIA I'm sure is behind this, in my opinion," Birkenfeld said.
